Personnel Device --> Multi-Access Edge Computing:
personnel location
This flow may also be implemented by
Personnel Device --> Connected Vehicle Roadside Equipment: personnel location Definitions
personnel location (Information Flow): The current location (latitude, longitude, and elevation) reported by the personnel device.
Personnel Device (Source Physical Object): 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.
Multi-Access Edge Computing (Destination Physical Object): 'Multi-Access Edge Computing' ((MEC) previously known as mobile edge computing) represents computing devices that operate and are managed like a cloud server, but are deployed at the edge of a network (typically a cellular network, but it could be any network). While not in strict proximity to the transportation network, these systems do benefit from vastly decreased distances to the roadway compared to central systems, and so can provide lower latency than strictly backoffice systems

| Basis | This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. | An incorrect locations message, could lead to a false warning or lack of warning. A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. | There are other visual indicators about the geofenced areas. Personnel device users in dynamic environments (incident and work zones) should know when they are leaving a geofenced area. As long as they remain in the geofenced area, this information is not as necessary. Not all personnel will carry a personnel device, and the system should be able to operate without this information. | |
